Hi,
I am trying to get Ethernet to work through the USB port of the Sinlinx
SinA33 on U-Boot to use TFTP to get the kernel and dtb files.
However, I am getting 'data abort' when using dhcp or tftp after adding:
#define CONFIG_USB_HOST_ETHER
#define CONFIG_USB_ETHER_ASIX
to include/configs/sunxi-common.h and checking CONFIG_USB_EHCI_HCD as
told in the documentation [1]
I tested this configuration with the C.H.I.P. and it is working well.
Are you perhaps building u-boot with gcc6 ? There are some known issues
when building u-boot with gcc-6, which look pretty much like this.
No, I'm building with gcc-5:
$ arm-linux-gnueabihf-gcc --version
arm-linux-gnueabihf-gcc (Ubuntu 5.2.1-22ubuntu1) 5.2.1 20151010
Is the ethernet adapter connected to a regular usb host port, or to
the otg port ?
The Ethernet adapter is connected to the regular USB host port.
So I've been debugging some armv7 cache issues lately and I've come
up with the following fix:

This might very will fix your issue too. If not we're likely missing
some cache flushing / invalidation in the usb driver for your usb
host controller.

Steps to reproduce:
1) Add the following lines to include/configs/sunxi-common.h:
#define CONFIG_USB_HOST_ETHER
#define CONFIG_USB_ETHER_ASIX
2) make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf-
Sinlinx_SinA33_defconfig
3) make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
4) Check CONFIG_USB_EHCI_HC and save configuration
5) make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j$(nproc)
6) Prepare SDCard:
sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8
7) Boot the board and run dhcp or tftp
8) Get 'data abort' and board gets reset (ethact is also not defined)
The log file is attached.
Thank you,
Quentin
